i have to check that whether a call made on a number by code is success or not ,if not then i have to make another call on another number…..
-(IBAction)callPhone:(id)sender {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:2135554321"]];
}
You cannot. Apple does not provide you any information about calls at all. You won’t know whether the phone actually tried making the call (other than
openURL:might return NO if the URL was invalid or some other error occurred).This is by design and intended to protect the users’ privacy.
